3.3.9. Gas distribution phases



It is important for the correct adjustment of phases of gas distribution that the gear belt of the drive of the camshaft was correctly tense. Precisely it is possible to check a belt tension only by means of special Opel KM-510A adaptation.

1. Check a tension of a gear belt.
2. Install the N1 cylinder in VMT.
3. Adjustment is made with use of a measuring level of KM-238-2 and the MKM-571 indicator.
4. Instead of a measuring level it is possible to use a steel ruler to which the indicator fastens.
5. Establish a measuring level on the camshaft case.
6. Establish an indicator leg on the 2nd cam and to install the indicator on "0". This cam puts the inlet valve of the 1st cylinder in action. To be convinced that the leg of the indicator has a flat, but not convex surface.


To Opirat an indicator leg on a cam nape, but not on its ledge!

7. To apply "0" and "10" (mm) on a measuring level of a tag.
8. To move the indicator with a measuring level in the direction of a cam ledge to a tag "10".
9. Weaken fastening of the cogged pulley of the camshaft.
10. A wrench on 22 mm to turn the camshaft clockwise until the leg of the indicator does not rise by 0,55±0,05 mm.
11. Holding the camshaft in this situation, to screw a new bolt of fastening of the cogged pulley and to tighten its moment 75 Nanometers. After that to tighten a bolt on 60-65 °. At an inhaling the camshaft provorachivaniye is not allowed.


After fixing of a pulley of the camshaft to double-check gas distribution phases.

12. Check an injection advancing, if necessary to modify.
